Danica’s Arduino Homework 2

I choose the two buttons control one LED (on and off), and click either or both of the button can turn the LED off.

Here is the circuit and code:

const int buttonPin1 = 2;
 const int buttonPin2 = 7;//the number of two button pin
 const int ledPin =  13;      // the number of the LED pin
 // variables will change:
 int buttonState1 = 0; 
 int buttonState2 = 0;// variable for reading the pushbutton status
 void setup() {
   // initialize the LED pin as an output:
   pinMode(ledPin, OUTPUT);
   // initialize the pushbutton pin as an input:
   pinMode(buttonPin1, INPUT);
   pinMode(buttonPin2, INPUT);
 }
 void loop() {
   // read the state of the pushbutton value:
   buttonState1 = digitalRead(buttonPin1);
   buttonState2 = digitalRead(buttonPin2);
 // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
   if (buttonState1 == HIGH&buttonState2==HIGH) {
     // only when two button is off when turn LED on:
     digitalWrite(ledPin, HIGH);
   } else {
     // turn LED off:
     digitalWrite(ledPin, LOW);
   }
 }

ps: I tried to embed the Tinkercad link, but I couldn’t find the project in my own Dashboard, it’s missing. SoI can only share the link.
